About USYMRO® (ustekinumab)

USYMRO® is a biosimilar to Janssen’s Stelara® which is a human monoclonal antibody that inhibits the bioactivity of human IL-12 and IL-23 by preventing shared p40 subunit from binding to the IL-12Rβ1 receptor chain of IL-12 (IL-12Rβ1/β2) and IL-23 (IL-12Rβ1/23R) receptor complexes on the surface of immune cells. IL-12 and IL-23 are involved in inflammatory and immune responses, such as natural killer cell activation, CD4+ T-cell differentiation and following relative cytokines stimulated release. Abnormal regulation of IL-12 and IL-23 have been implicated as important contributors to chronic inflammation, including psoriasis, psoriatic arthritis (PsA), and Crohn’s disease (CD). Neutralizing human IL-12 and IL-23 by USYMRO® to prevent the relevant cell signaling in the Th1 or Th17 lineages can effectively block the pathologic processes of these immune disorders.
